1. What are the advantages of LED display screens in traffic control?
The brightness of LED display screens is very high, and drivers and pedestrians can see the information on them effortlessly, even outdoors in direct sunlight.
For example, at traffic intersections, the display screen can clearly display road conditions, speed limit prompts, safety warnings, and other content.
This high brightness and high contrast display effect ensures the accuracy and reliability of information transmission.
Imagine that in the hot sun, ordinary display screens may be reflective or blurry, but LED display screens can still let you see clearly, which is crucial for traffic safety.
The LED display screen can update traffic information in real time, which is one of its highlights.
For example, the traffic management department can update information such as whether the road ahead is congested, whether there are accidents, or construction at any time through the background system.
During driving, drivers can use these display screens to understand the road conditions in advance and choose the best route.
This real-time nature makes traffic information more valuable and reduces the possibility of drivers getting stuck in congestion due to information lag.
LED display screens can not only display text information, but also graphics and animations.
For example, arrows can be used to indicate the direction of the vehicle, or animations can be used to display complex traffic rules.
This diverse display method makes it easier for drivers and pedestrians to understand the information.
For example, at complex intersections, animated arrows can intuitively tell drivers which direction to go, reducing confusion caused by misunderstanding traffic rules.
By displaying real-time road conditions and traffic prompts, LED display screens can help drivers adjust their routes in advance and avoid congested sections.
This function is particularly important during peak hours. For example, on urban main roads, display screens can guide vehicles to choose less congested routes, thereby improving overall traffic efficiency.
This is very helpful in relieving the pressure of urban traffic and making the driver’s travel smoother.
LED display screens can display safety tips such as “slow down”, “watch out for pedestrians”, “school area”, etc., to remind drivers to pay attention to safety.
These tips are particularly important in specific areas (such as near schools, near 医院, construction areas, etc.) and can effectively reduce the occurrence of traffic accidents.
For example, at intersections near schools, LED display screens can display the prompt “school area, slow down”, reminding drivers to reduce speed and pay attention to pedestrian safety.
LED display screens can work stably under different environmental conditions, including high temperature, low temperature, humidity, etc.
This means that no matter how the weather changes, the display screen can continue to provide accurate traffic information.
For example, in the winter in the north, the temperature is particularly low, and many equipment are prone to problems, but the LED display screen can still work steadily to ensure that the transmission of traffic information is not affected.
Traffic management departments can remotely control and monitor LED display screens through the network, update information in real time, and monitor equipment status.
Once a problem is found, maintenance can be arranged quickly to ensure the normal operation of the equipment.
This remote control function makes traffic management more efficient and reduces the frequency and cost of manual inspections.
By displaying road conditions in real time, LED displays can help drivers avoid congested sections in advance and effectively relieve traffic pressure.
On urban main roads or highways, the display of such real-time road conditions can significantly increase traffic flow and reduce congestion time.
This is very helpful for improving the overall operating efficiency of urban traffic and making drivers’ travel smoother.
LED displays can be integrated with intelligent transportation systems to realize the automatic collection and display of traffic information.
Traffic management departments can adjust traffic rules based on real-time data and improve the intelligence level of traffic management.
For example, by integrating with traffic monitoring cameras, sensors, and other equipment, LED displays can display road conditions, traffic flow, and other data in real time, helping traffic management departments to better manage traffic and improve the overall operating efficiency of urban traffic.
2. Application of LED displays in traffic command centers
1). Visual presentation of traffic data
Imagine that the traffic command center is like a “traffic brain”, and the large LED screen is the eye of this brain.
It can make all kinds of complex traffic data simple and easy to understand, so that staff can understand it at a glance.
For example, the road flow heat map is like a colorful map; green means unobstructed, yellow means a little slow, and red means very congested.
When staff see the red area, they know where the congestion is and they have to deal with it quickly.
There is also a speed distribution map, which can show the speed of vehicles on different sections of the road.
If you find that the speed of vehicles in a certain place suddenly slows down, there may be a problem.
Another example is the congestion index curve, which is like a fluctuating line that can tell staff how the congestion changes, whether it is getting more and more congested or slowly easing.
With these intuitive displays, staff can quickly find problems, make decisions, and make traffic smoother.
2). Integration and switching of monitoring images
In the traffic command center, the LED screen is like a “super monitor” that can concentrate the images of many cameras on a large screen.
These cameras are distributed at various key intersections, sections, and transportation hubs, just like many pairs of eyes watching the traffic situation.
Staff can see the situation in multiple places on the big screen at the same time, without switching back and forth, they can fully grasp the actual traffic situation.
Moreover, if there is a problem in a certain place, such as a traffic accident or someone violates the rules, the staff can quickly switch to the picture of that camera and check the situation carefully.
The big screen can also splice several pictures together to form a larger perspective, allowing staff to see more clearly.
In this way, they can discover and deal with various emergencies in time and reduce congestion caused by accidents and violations.
3). Emergency command and coordinated dispatch
When encountering traffic emergencies, such as traffic accidents or road construction, the LED big screen becomes the “baton” of the command center.
It can display the emergency response plan in real time and tell the staff what to do, such as what to do first, what to do later, and which steps cannot be missed.
At the same time, the location and status of various departments such as the traffic police, road administration, fire, and medical care can be seen on the big screen, just like a “rescue map”.
Based on this information, staff can quickly deploy rescue forces and let various departments work together.
For example, traffic police go to divert traffic first, fire and medical care rush to rescue, and the road administration goes to clear the road.
The large screen will also display traffic control measures, such as where it is closed and where the speed limit is set, so that all departments can adjust their actions in time.
Through the sharing of this information, all departments can respond quickly, restore traffic order as soon as possible, and reduce the impact of congestion on everyone.
4). Decision support and analysis
The LED large screen is not only an “eye”, but also a “think tank”. It can work with traffic analysis software to analyze historical data and real-time information and provide useful suggestions to staff.
For example, it can predict traffic flow, tell staff which sections of the road may be congested, and prepare in advance.
It can also analyze congestion trends to let staff know whether congestion is getting worse or easing.
The large LED screen will also provide an optimization plan for signal timing, just like an intelligent “traffic commander” telling staff how to adjust the time of the signal lights to make the traffic flow at the intersection smoother.
With these decision supports, staff can take measures in advance to alleviate congestion and make the entire traffic system run more efficiently.
3. Application of LED display screens in urban roads
1). Intersection guidance screen
At the main intersections in the city, the LED guidance screen is like a “traffic guide”. It will display the current congestion situation at the intersection and tell you whether the road is smooth or not with intuitive icons or text.
For example, it may display a red “congested” or a green “smooth” so that you can understand the road conditions at a glance.
It will also display the estimated travel time, telling you how long it will take to pass the intersection.
More importantly, it will recommend alternative routes in the surrounding area, just like an intelligent navigation system.
When you are approaching the intersection, you can see the information on the induction screen and adjust the driving direction and route in time according to the actual situation to avoid entering the congested section.
In this way, the traffic flow of the entire road network can be more balanced, the road’s traffic capacity will be improved, and everyone’s travel will be smoother.
2). Road section information screen
On both sides of urban trunk roads, highways, and other sections, the LED information screen is like a “road information announcer”. It will release real-time traffic conditions and tell you whether the road ahead is smooth or congested, and whether there are any accidents.
If there is road construction, it will notify you in advance so that you can be prepared to slow down or change lanes.
Traffic control notices will also be released in a timely manner. For example, if a certain section of the road is restricted, it will tell you how to detour.
There are also weather warnings, such as heavy rain and fog, which will remind you to drive safely.
When the driver sees this information while driving, he can prepare countermeasures in advance, arrange travel plans reasonably, reduce parking and deceleration caused by emergencies, keep traffic flow smooth, and avoid chaos due to unexpected situations.
3). LED display screen for bus lanes
The LED display screen on the bus lane can be said to be the “smart assistant” of the bus. It will display the real-time location of the bus, so that you can know how long it will take for the bus to arrive at the platform.
The arrival time will also be accurately displayed, so that passengers can arrange their waiting time reasonably and will not wait in vain.
The vehicle load will also be displayed, such as telling you whether the bus is already crowded, and you can choose to wait for the next one.
This information improves the transparency and reliability of bus operations, making passengers feel that taking the bus is more convenient and reliable.
In this way, more people will be willing to choose public transportation, reduce the use of private cars, and thus alleviate the pressure of traffic congestion.
At the same time, this will also help improve the operating efficiency of public transportation vehicles, optimize the urban traffic structure, and make urban traffic greener and more efficient.
4. Application of LED display screens in highway traffic
1). Highway information board
On the highway, the LED information board is like a “clairvoyant” for the driver. When you are driving on the highway, you may not know the situation of the road ahead, but the information board will tell you.
For example, it will show whether the road ahead is unobstructed, whether there has been an accident, and how serious the accident is, so that you can prepare in advance, slow down, or change lanes in advance.
If there is construction ahead, the information board will also notify you in advance, telling you the specific location and expected end time of the construction, so that you can have an idea.
The information board will also show the location of the service area, including how far away from the next service area, whether there are gas stations, restaurants, toilets, and other facilities in the service area, which is particularly useful for drivers who drive long distances.
In addition, it will display the toll standard so that you know how much you have to pay in advance and avoid being in a hurry at the toll station.
With this information, drivers can plan their trips in advance, choose appropriate routes and service areas, and avoid traffic congestion and delays caused by untimely or inaccurate information.
At the same time, highway management departments can also release traffic management and safety tips through information boards in a timely manner, such as warnings of severe weather and speed limit adjustments, to ensure the safety and smooth flow of highways.
2). Toll station LED display
At the toll station, the LED display is like an “intelligent traffic commander”. It will display the toll rate in real time so that you know how much you have to pay before entering the toll station and so that you can prepare changes in advance or adjust the payment method.
The LED display will also display lane opening and closing information, telling you which lanes are in use and which lanes are temporarily closed, so that you can choose a smooth toll lane in advance to avoid queuing in front of the toll station.
The LED display will also show the traffic flow. If the traffic flow in a lane is particularly large, you can switch to a lane with less traffic in advance to reduce waiting time.
With this information, drivers can get the relevant information in time before entering the toll station, prepare in advance, choose the unobstructed toll lane to pass, reduce the waiting time of vehicles, improve the traffic efficiency of the toll station, and avoid traffic congestion caused by toll problems.
At the same time, toll station staff can also better manage the toll work through the display screen, adjust the lane usage in a timely manner, and ensure the efficient operation of the toll station.
Through the application of these LED display screens, the management of highway traffic has become more intelligent and efficient, which not only improves the traffic capacity of the road but also improves the travel experience of drivers, making highway traffic smoother and safer.
5. 结论
The application of LED display screens in traffic command has brought new hope for solving traffic congestion problems.
From data visualization in the traffic command center to real-time traffic condition prompts on urban roads, to intelligent guidance in highway traffic, LED display screens are gradually changing our travel experience with their unique advantages.
